[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] To address the aforementioned issues, the applicant has proposed a deboning flat file with an internal liquid channel.

[0034] Please see Figure 2 , Figure 2 An exploded view of a deboning flat file with an internal liquid channel provided in an embodiment of this application. The deboning flat file with an internal liquid channel includes: an outer tube 1, a first connecting tube 2, an inner tube 4, a middle tube 3, a liquid channel boss 41, a flat file assembly 5, a positioning pin 31, and a drive shaft 6.

[0035] The outer tube 1 can be provided with a first connecting tube 2 at one end, the inner tube 4 is provided inside the outer tube 1, and a liquid channel boss 41 can be provided on one side of the inner tube 4. The middle tube 3 is located between the inner tube 4 and the outer tube 1 in an annular cavity. One end of the middle tube 3 is connected to one end of the first connecting tube 2. The positioning pin 31 can be provided at the other end of the middle tube 3 to fix the connection between the outer tube 1 and the middle tube 3. The flat file assembly 5 is connected to the first connecting tube 2, and the drive shaft 6 is located in the inner tube 4 and connected to the flat file assembly 5.

[0036] The above-described design incorporates an inner tube 4 fitted onto the drive shaft 6, a middle tube 3 fitted over the inner tube 4, and an outer tube 1 fitted over the middle tube 3. These three components together form a smooth liquid channel, ensuring free flow of liquid within this channel. Furthermore, a locating pin 31 securely connects the outer tube 1 and the middle tube 3, enhancing structural stability and facilitating installation and maintenance.

[0037] In this embodiment, reference Figure 3 , Figure 3 This is a schematic diagram of the inner tube structure of a bone-removing flat file with an internal liquid channel provided in an embodiment of this application. The inner tube 4 can also be provided with a first groove 42 and a second groove 43 that are staggered to each other on both sides, which can ensure that the liquid can flow through and contact the drive shaft 6, thereby effectively reducing the heat accumulation during the operation. It can also make the outer tube 1, which is sleeved outside the middle tube 3, flexible and flexible according to the surgical needs, greatly expanding the surgical field of view and providing doctors with a wider operating space and a more precise operating angle.

[0038] In addition, a first connecting pipe 2 can be provided at one end of the outer tube 1. When the first connecting pipe 2 is inserted into the outer tube 1, it can be fixed to the outer tube 1 by welding, ensuring the stability and sealing of the connection. The other end of the first connecting pipe 2 can also be provided with a third groove and a bearing mounting section 7. The bearing mounting section 7 is connected to the third groove, providing reliable support for the precise installation of the bearing.

[0039] Meanwhile, the bearing mounting section 7 may include a fixing seat 71 and a positioning groove 72. The fixing seat 71, as the core component of the bearing mounting section 7, is embedded inside the bearing mounting section 7 to ensure accurate and stable bearing installation. The positioning groove 72 can be located at one end of the bearing mounting section 7 near the third groove, providing a reliable basis for positioning the fixing seat 71. (Refer to...) Figure 4 , Figure 4This is a schematic diagram of a fixing base 71 for a deboning flat file with an internal liquid channel, provided in an embodiment of this application. A positioning boss 712 can be provided on the upper part of the fixing base 71. The positioning groove 72 and the positioning boss 712 further improve the installation accuracy and reliability. A liquid channel clearance groove 711 can also be provided on the lower part of the fixing base, effectively preventing liquid from interfering with the bearing mounting section 7 and providing a channel for smooth liquid flow, thereby ensuring the normal operation of the entire structure.

[0040] Furthermore, the applicant has discovered that while some electric flat files are equipped with liquid channels, the diameter of these channels is designed to be too large, requiring more space to accommodate them. This prevents them from reaching some narrow or complex locations, thus limiting the scope and precision of the surgery. The applicant provides a bone-removing flat file with an internal liquid channel, which also includes a flat file assembly 5. The flat file assembly 5 includes a second connecting pipe 51, a bent section 52 of the file head, and a bone-removing file head 53. One end of the bent section 52 of the file head is connected to the bone-removing file head 53 to ensure flexibility during use. The diameter of the bone-removing file head 53 has been carefully considered and is preferably 3mm-10mm to adapt to different surgical needs. In addition, the bone-removing file head 53 can also be flexibly installed in a third groove, improving the ease of use. The other end of the bent section 52 of the file head is connected to one end of the second connecting pipe 51, and the other end of the second connecting pipe 51 is connected to the drive shaft 6. The bent section 52 of the file head is connected to the drive shaft 6 through the second connecting pipe 51. This connection method can be achieved in various ways, such as crimping at both ends, threaded connection, welding, or adhesive bonding, thereby meeting the needs of different application scenarios. The flat file assembly 5 not only has excellent performance and stability, but can also adapt to various complex surgical operations, providing great convenience for doctors.

[0041] In addition, the cross-sectional shape of the curved section 52 of the file can be circular, oblong, or other shapes. The circular cross-section design can provide uniform cutting force and good rotational stability, making it suitable for most routine surgical scenarios; while the oblong cross-section design can reduce damage to healthy tissue while ensuring cutting efficiency, making it particularly suitable for complex surgeries with extremely high precision requirements.

[0042] In terms of materials, the bent section 52 of the file can also be made of high-strength, corrosion-resistant materials such as stainless steel and titanium alloy. Stainless steel has good mechanical properties and wear resistance, which can meet the strength and durability requirements of most surgical instruments; while titanium alloy, with its lightweight, high strength and good biocompatibility, has become the preferred material for high-end surgical instruments, which can further improve the precision of surgery and patient comfort.

[0043] To ensure a more secure connection between the inner tube 4 and the middle tube 3, a fixing plate 32 can be provided on the middle tube 3. The fixing plate 32 can enhance the connection strength between the inner tube 4 and the middle tube 3 through its own deformation characteristics, and also ensure that the two will not easily loosen due to external forces during use.

[0044] A positioning pin 31 can also be set on the middle tube 3. The outer tube 1 and the middle tube 3 are stably connected by the positioning pin 31, which allows the osteotome to withstand greater pressure and vibration during the operation, thereby ensuring the accuracy and safety of the operation. This not only enhances the stability of the structure, but also simplifies the installation and maintenance process. Doctors or technicians can easily and quickly assemble and disassemble the outer tube 1 and the middle tube 3 through the positioning pin 31. This not only improves work efficiency, but also provides great convenience for subsequent cleaning, maintenance and repair work.

[0045] To ensure a more secure fixation between the inner tube 4 and the middle tube 3, a fixing plate 32 can be added to the middle tube 3. With its excellent deformability, the fixing plate 32 effectively enhances the connection strength between the inner tube 4 and the middle tube 3, thus ensuring that they do not easily loosen even under external forces during surgical procedures. The design of the fixing plate 32 not only improves the stability of the overall structure but also provides a solid guarantee for the smooth progress of the surgery.

[0046] The bone-removing flat file with a built-in liquid channel provided in this application may also include a handle 9. A water channel connecting pipe 91 may be provided in the handle 9. The water channel connecting pipe 91 is connected to the outer pipe 1 to form a smooth liquid transmission channel. The liquid flows through the water channel connecting pipe 91, through the liquid channel boss 41, in the outer pipe 1, and then flows out through the liquid channel relief groove 711.

[0047] To achieve a detachable connection between the second connecting tube 51 and the drive shaft 6, a threaded connection can be used. Specifically, the inner wall of the second connecting tube 51 has an internal thread that perfectly matches the external thread of the drive shaft 6. During assembly, the drive shaft 6 is inserted into the second connecting tube 51, and by rotating the drive shaft 6, the two are tightly locked together. This connection method is not only simple to operate but also stable and reliable, capable of withstanding large workloads. More importantly, it also has excellent vibration resistance, ensuring a stable connection between the second connecting tube 51 and the drive shaft 6 even in complex and changing environments, thus improving the overall efficiency of the deboning flat file.

[0048] In addition, the first connecting tube 2 may have a bend. The first connecting tube 2 having a certain angle can not only ensure that the flat file can directly reach the lesion site, thereby avoiding unnecessary damage to the surrounding healthy tissue, but also avoid obstructing the operator's view.

[0049] Generally, the angle of the bend can be adjusted within a certain range to adapt to the needs of different surgical scenarios. For example, in some complex or narrow surgical areas, a larger bend angle may be needed to ensure that the first connecting tube 2 can reach the lesion site; while in other cases, a smaller bend angle may be needed to maintain the stability and precision of the operation. This not only improves the efficiency and success rate of the surgery, but also greatly reduces the workload of the surgeon during the operation, providing strong support for the smooth progress of the surgery.

[0050] Working principle: During the operation, the doctor inserts the file head of the bone removal file 53 into the area to be operated on and uses the bone removal file head 53 of the flat file assembly 5 to perform bone removal. The doctor opens the water connection pipe as needed. The liquid first enters the liquid channel boss 41 of the bone removal flat file smoothly through the water connection rod in the handle. Then, the liquid flows along the designed path. During the flow, it can cool the working area and help remove the generated debris. Finally, the liquid flows out through the liquid channel relief groove 711 to ensure a clear surgical field and smooth operation.
